分量の螢光体を付着させることは難かしかった。It has been desired to develop a material with good luminous efficiency, and a yttrium-based phosphor has been developed as a high-brightness material, but this material was expensive. On the other hand, attention has been paid to the fact that Caa 1 is an inexpensive and high-luminance phosphor, and the application of this to a picture tube fluorescer 1 [1c] is being considered. By the way, when this Caa-based phosphor is added to the conventionally commonly used PI-ADC-based photoreceptor slurry 17-, the slurry gels in about 10 minutes after adjustment, and the slurry is mixed into the inner surface of the face grate panel. Therefore, it was impossible to put the Caa-based phosphor into practical use as a phosphor for the f-quadrant. Recently, as a countermeasure to this problem, a method has been proposed in which a cloth is formed on the inner surface of the face plate panel using a material having appropriate adhesiveness and adhesion, and a front and rear phosphor is adhered to the inner surface of the face plate panel in the form of dry powder. (See Japanese Patent Publication No. 56-46642) However, even with this method, it was difficult to adhere a sufficient amount of phosphor to the inner surface of the face grating panel.
